Including a js file that does not exist

Looks like this plugin is including a js file (/assets/js/script.js) that doesn’t exist. It doesn’t cause an issue, it just doesn’t doesn’t seem to need to. Seems like it gets called in wpms-network-global-inserts.php in this function:

function load_script()
        {
            wp_enqueue_script('wpmsngi_script', WPMSNGI_URL . '/assets/js/script.js', array('jquery'));
        }

I am going to dequeue it wiht this:

add_action( 'wp_enqueue_scripts', 'remove_scripts', 99 );
function remove_scripts() {
	//Remove an 404 js file that the WPME Network Global Inserts plugin is including
	wp_dequeue_script('wpmsngi_script');
}
